Mitsui Kinzoku Group Conflict Minerals Policy

Mitsui Kinzoku Group promotes responsible mineral sourcing for corporate social responsibility and compliance, taking human rights, environment and laws/regulations into consideration.


As a member of the global supply chain, we set a policy of not using “conflict minerals※1” , if these minerals are the source of funds for armed groups who are violating human rights.


In particular, some conflict minerals mined in the Democratic Republic of the Congo (DRC) and its nine adjoining countries are suspected to benefit armed groups. Mitsui Kinzoku Group works with suppliers and the international industry initiatives to promote the use of conflict minerals that do not directly or indirectly finance or benefit armed groups in the covered countries.


  • We establish internal management systems and manage the supply chain appropriately in accordance with the OECD (Organisation for Economic Co-operation and Development) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.
  • Regarding the smelting business of tantalum and gold, Mitsui Kinzoku Group, as a responsible smelter, carries out due diligence for conflict minerals which utilized smelting. We have acquired the certification of Conflict Free Smelter (CFS) ※2 for the smelting business by undergoing third-party audits every year.
  • Regarding our products containing smelted conflict minerals, Mitsui Kinzoku Group carries out supply chain due diligence utilizing the Conflict Minerals Reporting Template (CMRT) developed by the CFSI※3 for supply chain risk management and disclose results if necessary.

  • Tin, Tantalum, Tungsten and Gold. Conflict minerals are defined as cassiterite, columbite-tantalite, gold, wolframite, or their derivatives, or any other minerals or their derivatives determined by the Secretary of State to be financing conflict in the DRC or its adjoining countries (Sourced by the section 1502 of the U.S. Dodd Frank Wall Street Reform and Consumer Protection Act).
  • The CFS Program and equivalent cross-recognized third-party audit programs included the LBMA’s Responsible Gold Program.
  • Conflict-Free Sourcing Initiative: An international industry initiative working for improvement of regulatory compliance and supporting companies’ responsible sourcing from conflict-affected and high-risk areas.

We request our suppliers to agree to the Conflict Minerals Policy for responsible supply chain and to cooperate with surveys and audits implemented by Mitsui Kinzoku Group.
